Join Precious Plastic Plymouth to make your own buttons from plastic bottle tops! Bring along your CLEAN plastic milk bottle tops (or any HDPE – it's marked with a triangle with the number 2 inside) or use the ones that we have from Exeter Scrapstore. Our peddle-powered bike shredder will help you to make the plastic into smaller pieces. This goes into our injection moulder, where the plastic gets heated up to around 200 degrees celsius, the molten plastic gets injected into a button mould. It cools very quickly and you can take away your new buttons in about 20 minutes! Suitable for adults and children 11+ This event is part of the Pile Up! programme running at Exeter Custom House 10th-29th June.
